Inventor: MITSUI YOSHITAKA
IPC: G06F21/10
Filed: 2000-05-30
Abstract: PROBLEM TO BE SOLVED: To obtain a recorder that can record a latter broadcast program onto a recording medium without missing in the case of receiving and recording two broadcast programs continuously onto the recording medium by recording a video image block of another broadcast program received first through cancel lation of an instruction of no recording when the other broadcast program is selected while the no recording is instructed. SOLUTION: When copy control information indicates permission of recording, a propriety flag for the recording of a video block received successively and stored in a propriety flag storage section 7 is set to '0', and in the case that recording of an electronic watermark is inhibited, the propriety flag stored in the propriety flag storage section 7 in set to '1' not to record the video blocks successively received. An electronic watermark read section 8 detects timing when a new PID is outputted from a control microcomputer 3 to a transport decoder 4 and resets the propriety flag in the propriety flag storage section 7 to '0' that denotes recording possibility. Thus, another broadcast program can be recorded.

The minimum values among the minimum values in the respective steps are then determined and the values of the regulation parameters at which the minimum values are resulted are decided as the finest parameter value. The minimum values among the maximum values in the respective steps are determined and the values of the regulation parameters at which the minimum values are resulted are decided as the complementary finest parameter values. The values of the regulation parameters meeting the ratios of the deformation of the optical disk are computed from the finest parameter values and the complementary finest parameter values.

Title: Constant flow valve
Inventor: OKADA SADAO
IPC: F16K1/54
Filed: 2000-06-14
Abstract: PROBLEM TO BE SOLVED: To provide a constant flow valve capable of eliminating such problems of the conventional constant flow valve that a controlled water volume varies as a water temperature varies, in which a flow passage area is varied by the elastic deformation of rubber and the performance depends largely on the physical properties of rubber. SOLUTION: This constant flow valve 2 does not cause such a problem that the hardness of a spring 14 varies as a water temperature varies and, even if the water temperature varies, does not cause such a problem that a control water volume varies, because a movable valve 12 receiving a hydraulic pressure is energized to the upstream side by the metal spring 14 to control the water volume. Since the movable valve 12 is supported by a resin square ring 13, the vibration of the movable valve 12 during the control of the water volume is suppressed, and the occurrence of abnormal noise such as whistling noise, pulsation noise, and vibration noise due to the flow of water can be suppressed.  Since the constant flow valve 2 is slidably supported on a valve case 11 by the peripheral surface of a pressure receiving plate 12b and the square ring 13, the axial dimension of the valve 2 can be shortened.

Title: Variable valve timing control device for internal combustion engine
Inventor: SATO OSAMU
IPC: F01L13/00
Filed: 2000-06-09
Abstract: PROBLEM TO BE SOLVED: To obtain the effect of improving fuel consumption by internal EGR without worsening the combustion state of an internal combustion engine. SOLUTION: An intake valve and an exhaust valve of the internal combustion engine are respectively provided with variable valve timing devices. In a low- rotation low-load region (but in a higher load region than idling time), exhaust valve early closing control is executed to close the exhaust valve at earlier timing than the intake top dead center, thus confining combustion gas remaining in a cylinder. Further, the opening timing of the intake valve is set to almost the intake top dead center or slower timing to compress residual gas in the cylinder by a piston in a period from the closing of the exhaust valve to the intake top dead center, thus heightening the temperature in the cylinder.  A mixture can thereby be taken into the cylinder in the state of the temperature in the cylinder being higher than that of the internal EGR based on a conventional valve overlap, so that the atomization of fuel in the cylinder is improved to stabilize the combustion state.
